Love for a teen is the same for an adult. I am 21 by husband 25. i met him when i was 15. I had a few other boyfriends as well when we had are break, and yet I knew something was different about him. When your in love you will know... sounds stupid but it's true.
There is no such thing as love for a teen due to all the hormones and all the mixed signals ect ect ect if there is anything there it might just be a strong lust almost every teenage relationship ends.
